Abstract: Tin dioxide is a traditional gas sensitive material. Owing to the gap of tin ion and the vacancy of oxygen, the detecting gas can be adsorbed on the surface of the material, which can demonstrate good gas sensing properties. It is a good way to discuss a series of gas sensors with good properties by means of noble metal-load and synthesis of composite oxides. In this article, the new development of tin dioxide gas sensor from the two aspects of gas sensor mechanism and development of materials are mainly elaborated.
